To aZZwLom it may concern:

Be it known that l, JOHN B. Biron, a subject of the King of Sweden,resid-ing at Chicago, in the county of Cook and State of lllinois, haveinvented certain new and useful Improvements in Roller Bearings, ofwhich the following is a specification.

This invention relates to improvements in roller bearings, and itconsists in certain peculiarities of the construction, novelarrangement, combination and operation of the various parts thereof, aswill be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a roller bearing,which shall be simple and inexpensive in construction, easily assembled,strong, durable, and eilicient in operation, with its part-s so made,arranged, and cooperating with one another, as to perform the functionsvof antifriction rollers heretofore in general use, and in additionthereto, adord means whereby load carrying rollers only are ujsed inconnection with the retaining rings or means thereof.

Still another object of the invention is to provide means to take careof or carry side thrusts of the parts and to reduce to a minimum, noiseincident to the operation of the various parts of the bearing. Stillanother object is to provide a bearin in which the rollers thereof willhave uniform and simultaneous bodily, as well as individual, movements.

@ther objects and advantages of the invention will be disclosed in thefollowing description and explanation.

ln the accompanying drawing, which serves to illustrate an embodiment ofthe invention@ l is a face view partly in elevation and partly insection of a bearing, showing the thereof in their operative positions.

Fig. Q is a central sectional view taken on line 2-2 of ll'ig. l lookingin the direction indicated by the arrows.

Fig. 3 is a side view of the bearing with the spacing elements for therollers removed, showing l y continuous lines the position or the partsin the first step of assembling the same and by dotted lines, the secondor following step in said operation.

Fig. t is a fraental sectional view of parts of the inner and outerretaining members or rings with a pair of the rollers interposedtherebetween and illustrating a modilicatltion in the construction ofthe device, an

F ig. 5 is a similar View of like parts illustrating another modifiedconstruction.

Like numerals of reference refer to correresponding parts throughout the'different views of the drawing.

Referring to the drawing, the reference numeral 7 designates the outerretaining member or ring of the bearing, which may be made of anysuitable size and material. This member "is made' of a single piece, andpreferably inthe form of a ring, but if desired, it may have its outerportion of other shape than circular. The inner surface of the peripheryof the ring 7 is inclinedyfrom each of its edges towards the outersurface of the ring to a point about midway between the sides of thering. rlfhe inner retaining --member or ring of the bearing is indicatedby the numeral 8, and is made of a single piece and of any suitablesize, but by preference of the same width as the outer ring, and isnormally concentrically located in said outer ring but spaced therefrom.

The inner ring 8 which may be suitably mounted on a journal or axle, hasitouter periphery inclined from each of the side edges thereof towardsthe outer ring, .as is clearly shownl in F ig. 2 of the drawing, inwhich view it lwill be seen that while the inclined portions leadingfrom the edges of the outer ring andthe corresponding portions of theinner ring are inclined in the same direc* tion, yet it will beunderstood that the inu clinations of said parts are not located inparallel planes, but are so disposed that the space betweenthe/coinciding inclined portions of the inner and outer rings are widernear the inner or middle portions or apeires of said inclined walls,than at their outer ends.

By this arrangement an annular space having upwardly inclined andslightly con tract/ed walls from its middle portion is provided, inwhich a plurality of a-ntifrietion rollers 9 are located with thatportion of their inner ends adjacent the inner member 8 in contact withone another and in a of rows as will be readily understood by referenceto Fig. 2 of the drawing. Each of these rollers by preference has itsinner end slightly beveledA as at for -the purpose of permitting themembers of each pair of rollers contacting with each other at theiradjacent ends at points adjacent the inner retaining member.

Eachy of the rollers 9 is tapered from its inner portion or end to itsouter end to correspond with the tapered space between the outerretaining ring and the inner retaining ring between which the rollersare located.

As is clearly shown in Figs. 2, 4 and 5 the inner retaining ring 8 isprovided at each of itsedges and in its outer periphery with a circumferentially disposed angular recess 11 for the reception of membersof the ,spacing element for the rollers. This spacing element isdesignated-as a whole by the numeral 12 and consists of a flat ring 13having extendedfrom its inner surface at its outer periphery and atright angles to the ring a series of spaced arms or bars 14 each ofwhich has at its free end a tongue 15 or reduced portion adapted tofitin openings 16 of anotherring 17 which is located at its innerperipheryin the groove or recess 11 of the inner retaining memberopposite the recess 11 in which the ring 13 is located.

Y Each of the arms or bars 14 is provided at each of its edges with aninturned flange 18 between which the rollers the drawings I haveillustrated a modification in the construction of the rollers of thedevice, the other parts thereof being of substantially the sameconstruction and arrangement as above set forth. 1n this modificationeach of the rollers 9 is provided in its inner end with a depression 19in which is located between the members of each pair of rollers, a ball20 used for compensating for the wear incident to the contactingportions of the members of each pair of rollers. ri`hat is to say, thatshould the contacting portions of each pair of rollers become worn to asufficient degree to decrease their edi ciency, the balls 2O will vactto support them in a similar manner as before they become worn. f

lin Fig. 5 l have illustrated still another modification in which theconstruction of the parts are the same as that shown in Figs. 1 to 3inclusive and first above described ex'- cept that each member of eachpair of the rollers 9. is provided in its inner end with a nest orcavity 21, in which and between the members of each pair of rollers islocated a spiral spring 22 which is employed to perform the samefunction as the balls 20 above described in connection with themodification shown in Fig. 4 of the drawing. lin order to assemble theparts of the bearing, the outerA retaining member or ring may beplacedin about the position shown 9 are located after' the partshavebeen assembled. 1n Fig. 4 of 7 tending at right in Fig. 3 of thedrawing, whena plurality of load carrying rollers 9 may be placed in apair of rows on the inner surface of the said retaining member, and whenthe balls 20 or springs 22 are employed, with a ball 20 or a spring 22between the inner ends of each pair of the rollers, in which positionsaid balls and springs will be 'retained by reason of the depressions 19and nests 21, in which said balls andsprings cated. The,arrangement ofthe rollers in the first step of assembling the parts is shown bycontinuous lines in Fig. 3 of the drawing,

in which view it will be seen and understood that the inner retainingring 8 is then placed eccentrically within the outer retainin ring 7 asshown by continuous lines in said gure, when by causing the inner tovassume the dotted line position, it is manifest that the rollers 9 canbe moved between the inner and are respectively loouter retainingmembers and properly spaced. K y

When the rollers are thus arranged, the

ring 13 of the spacing element 12 which carries the arms 14 extendedfrom the inner surface of said ring can be placed between the retainingrings 7 and 8 at one of their edges in such a manner' that said ringwill rest in one of the annular recesses 11 of the inner retainingmember while the arms 14 with their flanges 18, will be interposedbetween .the pairs of rollers as will be understood by reference to Fig.1 of the drawing.

When the spacing-element has thus been loi cated the detachable ring 17having the openings 16 therein for the reception of the tongues 15 onthe free ends of the arms 14 may be placed on the opposite side of theinner retaining member 8 within the recess 11 thereof, when it willbeunderstood that thetongues 15 will enter said openings and may beriveted or otherwise ined to the last named ring.

Having thus fully what il claim as new Letters Patent is- 1. 1n a rollerbearing, the combination with a single piece innerv bearing memberhaving its outerv periphe inclined outwardly from each of its egcs, of asingle piece cuter bearing member having its 1nne'r periphery outwardlyinclined from each of its edges, a .plurality of oppcsitely taperedrollers located between said members described my invention, and desireto secure by lin pairs with their larger ends facing and in contact witheach other, and means to hold said pairs of rollers in spaced relationcircumferentially with respect tc thesaid bearing members, said spacingmeans embodying a ring seated on the inner bearing member at one of theperipheral edges thereof and having a plurality of arms exanglestherefrom across the periphery of the inner bearing memr, each ieumelones of said arms haring on each of iis sidessan inwardly deecled:flange and ai ils free end a tongue, and anolsher ringr sealed on dieopposile peripheral edge of the inner hearing member and having spacedopenings lo receivfe *die longues on said arms.
